When disgraced gay London detective Lucien Knight arrives in 1930s New York seeking a fresh start, he doesn't expect his first client to be a glamorous socialite with a secret-and a ghost. Clara Beaumont insists the death of her lover, jazz singer Evelyn Sinclair, wasn't an overdose but murder. Drawn into the smoky allure of The Savoy Ballroom, Lucien discovers a world of speakeasies, mobsters, forbidden love, and melodies that hide deadly truths. But as he unravels Evelyn's past-and his own-Lucien realizes some secrets refuse to stay buried...and some ghosts refuse to stay dead.
